i have no safety settings on

LLC is off
no offset

manually set core voltage to 1.400

go to windows and check cpuz while idling.

volts go --> 1.392 --> 1.368 ---> 1.38 --> 1.356 --> 1.38.....

this is just messed up..

mobo : Asus M5A97 R2.0
cpu : fx-6100 4,3ghz

edit : forgot to mention, i started prime95 small fft test. vcore went to 1.344 and insta-crashed

Hi,

Sounds like Vdrop (difference between BIOS and idle voltage), not sure what you can do about that unfortunately

The difference between the idle and load voltage is vdroop which can be managed with LLC.

if i set LCC enabled, it increases vcore by 0,03-4 volts

example; i set 1.35 vcore in bios, under load goes to 1,368-1.396

Is that the only options you have for LLC? (Enabled and Disabled).

enable - disable - auto =/

oh and i tried offset mode too, set it to 0,1v, idle vcore was 1.412 volts and under load it dropped to 1.3xxx and crashed...

You could try using LLC (fixed not offset voltage) but compensate for the rise in voltage by putting in 0,03-4 less volts in the BIOS

Have you checked for a BIOS update? Maybe there's a new BIOS that gives you more control over LLC...

You might aswell keep up to date but I don't think it'll help with your vdroop issue.
